Page 119: What is an IO object ?
Listen to this article.
Value: Medium
Level: Easy
Summary:
In Ruby you can manage Input/Output in two ways. The first is to use methods implemented in the module Kernel (as gets(), puts(), etc.) that typically do I/O to standard input and standard output. The second is to create an object of the IO class. Such an object is "a bidirectional channel between a Ruby program and some external resource": you'll read from it and/or write to it.
Memo: None
Example: None
